What is the purpose of an inverter?

An inverter converts direct voltage from batteries or direct bus to alternating voltage, normally 220 Vca with output stabilization and in the form of a 50 Hz sinusoidal wave. This wave is often cleaner that the one obtained from the electrical network. The sinusoidal inverters are used to supply all kinds of load, whereas the “square”, “pseudo sinusoidal” or “modified sinusoidal” wave shape has certain limitations given its effect on inductive or capacitative loads. It is also important to mention that the noise or interference that can cause equipment such as precision instrumentation, telecommunication, etc. to function incorrectly. The main advantage is the price as it is often less than half what a sinusoidal device would cost for similar power.
